Which of the following statements is/are true.

(1) The apoplastic movement of water occurs exclusively through the cell wall without crossing any membranes.

(2) Solutes present in a cell (or in any solution) increases the free energy of water or water potential.

(3) The symplastic movement occurs from cell to cell through the plasmodesmata.

(4) Membrane permeability depends on the membrane composition, as well as the chemical nature of the solute.
